TR3 Mini Dual 6DJ8 ECC88 E88CC CCA Tube Valve Preamplifier Preamp For Amplifier Good choice for modification of DAC / CD player or guitar amplifier etc Add tube sound to audio system,Make it more musical&smooth High Lights TR3 tube buffer is based on dual 6N11 dual triodes tubes,6N11 have a bulk subsitution include 6DJ8/ECC88/E88CC/CCA,It is very musical tube with excellent extention at high frequency and very low noise,Also great driving ability with higher current than other tube buffer with 6J1 or 6N3(5670). It is designed for audio purpose,Users can use bulk tubes to taste different sounding. TR3 tube buffer is powered with DC 265V B+ voltage, First stage to preamplify the input signal and second stage is cathode follower,It is a great combination. 6922 tube is not compatible with the preamp as the voltage between cathode and anode is too high for it. 6DJ8/ECC88/E88CC/CCA would work with the preamp. Filament power supply is 6.3V DC or AC, Two tubes can share one group input power. TR3 is in very small size of 101mm* 50mm(PCB size), Can be installed in audio equipments which has not enough room for big tube buffer. TR3 use dual side PCB board layout, Components can be mounted on two sides except tube socket,Users can install big components on the PCB, It is very flexiable High quality components used on the tube buffer, Resistor is 1W metal film with low temperature drift,The resitor has copper legs which is more better than iron. Output capacitor is quality MKP caps(Red coaxial capacitor,We have done many comparasion and found it is the best for the tube buffer). Gold plated PCB board Specifications Tube: 6N11*2 Size: 101mm(W) * 50mm(D) * 68mm(H,include tube and resistor) Power Input: DC 265V for B+, 6.3V DC or AC (For filament, Pin 4 and 5 of tube socket) Gain: 8DB Output impedance: 450 Ohm Packing List One 6N11/6DJ8/ECC88/E88CC/CCA tube preamplifier About Chinaaudiostore We are a team composed of audio enthusiast, We are proferssional in analog and digital electric, More than just reseller.
